Could be a loose element in the muffler that vibrates at certain engine RPM. Or a small hole in the muffler. Sometimes the problem is as simple as a loose clamp, either a clamp that holds the muffler to the chassis or a clamp that joins two exhaust pipes. A loose clamp can allow the muffler or pipe to vibrate against the frame. Clamps are cheap - a lot cheaper than a new muffler or exhaust system.
Yes it is very easy to change a muffler depending if you got the right tools take a grinder or hack saw and if the muffler is welded cut in front and in back get 2 pipe conectores if needed some u bolts or welded and good to go
If the muffler is literally falling apart, I would replace it before you take it to get it safety inspected. If it just has a small hole in it and has no chance of it literally coming apart, then I wouldn't worry about it. So technically, it's not necessary to replace the muffler for a safety inspection but it'll be up to who is inspecting the car if he decides to have you replace it or not. So if the muffler is "rough" , I would replace it. If it's still in good shape, then I wouldn't bother replacing it.
If they don't require emissions where you're going to take the Bronco, as long as your lights, horn, signals, etc all the required things are working, you shouldn't have a problem with it. The fact that the muffler was bad when you went to emissions, this is the reason why it failed there.
